3x18 - Third Watch

Hopelessly in love with Kylie and concerned that she will lose her Latina heritage if she is adopted by a white couple, Carlos considers raising her until he realizes that the couple can give her the sister, the grandparents, and the extended family that he cannot; Kim's preoccupation with her new PDA drives Alex crazy until they are able to use it to save a very sick man, thus redeeming themselves in the eyes of a hypercritical Dr. Peterson; Faith and Fred are still on uneven ground about the sergeant's exam; in an effort to shake Chevchenko's tree, Faith and Sully execute a clever plan to disrupt the Russian's bookmaking operation, which also opens the door to the possibility of the still-missing Tatiana's return; Bosco is cleared for duty, and he and Faith agree to be partners again as soon as he returns.
